commit bfe11d6d upstream. When persistent grants were added they were always used, even if the backend doesn't have this feature (there's no harm in always using the same set of pages). This restores the old data path when the backend doesn't have persistent grants, removing the burden of doing a memcpy when it is not actually needed. Signed-off-by:

commit fbe363c4 upstream. There's no need to keep the foreign access in a grant if it is not persistently mapped by the backend. This allows us to free grants that are not mapped by the backend, thus preventing blkfront from hoarding all grants. The main effect of this is that blkfront will only persistently map the same grants as the backend, and it will always try to use grants that are already mapped by the backend. Also the number of persistent grants in blkfront is the same as in blkback (and is controlled by the value in blkback). Signed-off-by:

commit 5a838c3b upstream. pcpu_chunk_struct_size = sizeof(struct pcpu_chunk) + BITS_TO_LONGS(pcpu_unit_pages) * sizeof(unsigned long) It hardly could be ever bigger than PAGE_SIZE even for large-scale machine, but for consistency with its couterpart pcpu_mem_zalloc(), use pcpu_mem_free() instead. Commit b4916cb1 ("percpu: make pcpu_free_chunk() use pcpu_mem_free() instead of kfree()") addressed this problem, but missed this one. tj: commit message updated Signed-off-by:

commit b566e782 upstream. Having multiple windows with the same target and attribute is actually legal, and can be useful for PCIe windows, when PCIe BARs have a size that isn't a power of two, and we therefore need to create several MBus windows to cover the PCIe BAR for a given PCIe interface.

commit 4d595b86 upstream. After a @pwq is scheduled for emergency execution, other workers may consume the affectd work items before the rescuer gets to them. This means that a workqueue many have pwqs queued on @wq->maydays list while not having any work item pending or in-flight. If destroy_workqueue() executes in such condition, the rescuer may exit without emptying @wq->maydays. This currently doesn't cause any actual harm. destroy_workqueue() can safely destroy all the involved data structures whether @wq->maydays is populated or not as nobody access the list once the rescuer exits. However, this is nasty and makes future development difficult. Let's update rescuer_thread() so that it empties @wq->maydays after seeing should_stop to guarantee that the list is empty on rescuer exit. tj: Updated comment and patch description. Signed-off-by:

commit 77668c8b upstream. There is a race condition between rescuer_thread() and pwq_unbound_release_workfn(). Even after a pwq is scheduled for rescue, the associated work items may be consumed by any worker. If all of them are consumed before the rescuer gets to them and the pwq's base ref was put due to attribute change, the pwq may be released while still being linked on @wq->maydays list making the rescuer dereference already freed pwq later. Make send_mayday() pin the target pwq until the rescuer is done with it. tj: Updated comment and patch description. Signed-off-by:

commit 77f300b1 upstream. wq_update_unbound_numa() failure path has the following two bugs. - alloc_unbound_pwq() is called without holding wq->mutex; however, if the allocation fails, it jumps to out_unlock which tries to unlock wq->mutex. - The function should switch to dfl_pwq on failure but didn't do so after alloc_unbound_pwq() failure. Fix it by regrabbing wq->mutex and jumping to use_dfl_pwq on alloc_unbound_pwq() failure. Signed-off-by:

commit a1b8ff4c upstream. The nfsv4 state code has always assumed a one-to-one correspondance between lock stateid's and lockowners even if it appears not to in some places. We may actually change that, but for now when FREE_STATEID releases a lock stateid it also needs to release the parent lockowner. Symptoms were a subsequent LOCK crashing in find_lockowner_str when it calls same_lockowner_ino on a lockowner that unexpectedly has an empty so_stateids list. Signed-off-by:

commit 36189cc3 upstream. The hw_version 3 Elantech touchpad on the Gigabyte U2442 does not accept 0x0b as initialization value for r10, this stand-alone version of the driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2 Uses 0x03 which does work, so this means not setting bit 3 of r10 which sets: "Enable Real H/W Resolution In Absolute mode" Which will result in half the x and y resolution we get with that bit set, so simply not setting it everywhere is not a solution. We've been unable to find a way to identify touchpads where setting the bit will fail, so this patch uses a dmi based blacklist for this. https://bugzilla.kernel.org/show_bug.cgi?id=61151Reported-by:

commit 098507ae upstream. The replacement of the 'count' variable by two variables 'incs' and 'decs' to resolve some race conditions during module unloading was done in parallel with some cleanup in the trace subsystem, and was integrated as a merge. Unfortunately, the formula for this replacement was wrong in the tracing code, and the refcount in the traces was not usable as a result. Use 'count = incs - decs' to compute the user count.

commit 39236901 upstream. When probing with DT, we add each LED one at a time. If we find a LED without a PWM device (because it is not available yet) we fail the initialisation, unregister previous LEDs, and then by way of managed resources, we free the structure. The problem with this is we may have a scheduled and active work_struct in this structure, and this results in a nasty kernel oops. We need to cancel this work_struct properly upon cleanup - and the cleanup we require is the same cleanup as we do when the LED platform device is removed. Rather than writing this same code three times, move it into a separate function and use it in all three places.

commit 50c6e282 upstream. Various filesystems don't bother checking for a NULL ACL in posix_acl_equiv_mode, and thus can dereference a NULL pointer when it gets passed one. This usually happens from the NFS server, as the ACL tools never pass a NULL ACL, but instead of one representing the mode bits. Instead of adding boilerplat to all filesystems put this check into one place, which will allow us to remove the check from other filesystems as well later on. Signed-off-by:

commit 09da1f34 upstream. When we're performing reauthentication (in order to elevate the security level from an unauthenticated key to an authenticated one) we do not need to issue any encryption command once authentication completes. Since the trigger for the encryption HCI command is the ENCRYPT_PEND flag this flag should not be set in this scenario. Instead, the REAUTH_PEND flag takes care of all necessary steps for reauthentication. Signed-off-by:

commit 9eb1fbfa upstream. Commit 1c2e0041 introduced an event handler for the encryption key refresh complete event with the intent of fixing some LE/SMP cases. However, this event is shared with BR/EDR and there we actually want to act only on the auth_complete event (which comes after the key refresh). If we do not do this we may trigger an L2CAP Connect Request too early and cause the remote side to return a security block error. Signed-off-by:

commit 7040b6d1 upstream. The TEAC UD-H01 firmware sends wrong feedback frequency values, thus causing the PC to send the samples at a wrong rate, which results in clicks and crackles in the output. Add a workaround to detect and fix the corruption. Signed-off-by:
